IRF, insulated in-line duct fan

  • The insulated in-line duct fan IRF is designed and manufactured for high pressure ventilation systems with the benefit of a low operating sound level.
  • The low sound level is thanks to our design which has the advantage of high quality acoustic insulation which has an easy to clean facing applied to it during it's manufacturing process.
  • The casing are manufactured from galvanized steel sheets.
  • The insulated IRF has circular duct connection, and can be installed in cold environments.
  • IRF is fitted with a forward curved centrifugal fan; which is driven by a reliable maintenance free, ball bearinged, external rotor motor, speed controllable from 0-100%.
  • All our motors have approved built-in overheat protection, which can be supplied with external connection leads that could be used for an alarm function.
